vELECTRIC PULL-SWITCH.

Application led J une 23, 1917. Serial No. 176,500.v

To all whom t may concern:

Be it known that I, EARL H. VAN LooN, a citizen of the United States,residing 'at New York, in the county of New York and State of New York,have invented new and useful Improvements in Electric Pull-Switches,ofwhich the following is a specification.

This invention relates to a pull socket electric switch in which theactuating mechanism for making and breaking the circuit is provided withan arm projecting from the shell for attaching a flexible connection.

The invention is designed to comprehend means whereby the socket can bearranged in any desired position without disconnecting the flexibleconnection. y

The object of the invention is to provide readily accessible means forattaching the flexible connection so that when it accidentally breaks,it can be replaced on the arm by any unskilled person.

Heretofore in electric sockets of the-kind described above the flexiblepull was secured to the mechanism at the inside of the shell, hence whenthe connection was broken it became necessary to remove the cap from theshell and lift out the oscillatingdisk.

The invention resides in the novel combination of parts hereinafterfully, described and claimed, and illustrated in the accompanyingdrawing` in which:

Figure l represents a side elevation of a socket embodying thisinvention.

Fig. 2 is a transverse section taken along the line m of the same.

Fig 8 is a similar section showing the part-s in a different position.

In this drawing the letter a designates a shell provided with a cap bwhich when removed gives access to the interior of the shell. In theshell is secured a porcelain block c having mounted thereon anoscillating contact device including a disk fl for opening or closingthe electric circuit as is well known. In this device the'center ofoscillation oi' the make and break device is parallel withv thelongitudinal axis of the shell.

To thelower portion of the disk is secured at c an arm fhaving a slot gat its outer portion. The arm projects from a circumferential slot itformed in the shell. connection or chain z' has one end anchored orinserted in the slot of the arm. A spring hook shaped niousing y' coversthe entrance of Speecation of Letters Patent.

the slot and preventsthe chain from'jslipping out. The chain is threadedthrough an c velet secured to the outer portion of the shell. Thiseyelct is located slight-ly beyond the end of the slot as indicated inFig. 2. The eyelct being also in a direct line with the slot and arm, itwill permit an even pull of the chain and easy operation of the arm.

It will be readily understood -that the peculiar position of the chainguide in relat1on to the arm permits the socket to be placed in anyposition, for example, when used for an uprlght lamp, it can be invertedfromthe position indicated in Fig. 1 without disarranging the chain, orit can be placed horizontally or at any angle for a drop lamp. `When thechain is pulled the arm will slide along the segmental slot h in an arcof about 90 and the disk will swing in a cenccntric circle with theinner cylindrical portion of the shell.

As shown in the drawing the hook of the mousing engages the mouth of theslot e'ectively preventing the end of the chain from 'being accidentallypulled from the arm, but if the chain should be broken the end can bereleased from the slot by moving the spring hook outwardly.

I claim 1. A pull socketelectric switch comprising a shell having acircumferential slot. an oscillating device projecting through the slot,a connection secured to the oscillating device on the outside of theshell andmeans on the outside of the shell adjacent to the slot end forguiding the connection.

2. A pull socket electric switch comprising a shell having acircumferential slot, an

oscillating device extending through thev slot, a. connection secured tothe device and means on the outside of the shell adjacent to the slotend for guiding the connection.

3. A pull socket electric switch comprising a shell having acircumferential slot therein, an oscillating device extending throughthe slot, a connection `secured to the oscillating device and mea-ns lonthe outside of the shell so placed as to guide `the connection in suchway that the switch can be operated in any position or angle it may be placed in b v pulling on the connection.

4. A pull socket electric switch comprising a shell having acircumferential slot, oscillating devices for making and breaking thecircuit mounted in the shell, a slotted arm thc shell so placed as toguide the connection in such Way that the switch can he operated in an)vposition or angle it may belplaoed in 15 by pulling on the connection.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.

EARL H. VAN LOON.
